,r The invention vrelaties.generally toxj'hoists r and .moreparticularly to :power driven hoists capable of receiving the drivingpower vfrom a ysource such as a motorl vehicle. .-'I'The primary'objectofthe invention is to provide ay nevv'and improved" hoist which isadapted to be'readily attached to or removed`fromasuitable.sourceofpower. L v kIt has generallybeen'customary in theart pertaining to devices of this character to provide`hoistsinfwhich'ra reversing faction of the ypower drive -is-essential-toeffect a raising and vlowering movement thereof.

v Describing the invention first in` abrief general manner, 'the `(hoistcomprises la securing base` 10 preferably mounted perma-v 65 -nently onone of the wheelsll of a vehicle which is, in ,this instance, the leftreariwheel. The hoist proper' isY secured to the base lO in any mannerpermitting rapid. attachment4 and detachment therefrom and includes astub i shaftor auxiliary axle, generally designated 12, arranged torotate withthe wheel. -A vWinding drum 13 is rotatably mounted on theshaft 12 l.and has on one sidethereof'a driving Aconnection with theshaft. through vthe f intermediate agency ofjaclutch mechanism 14.' Thedrum is ,also arrangedtobe engaged bylmeans of arsuitable friction brakedevice 15l for preventingk the Jlrotation of the drum.

v Anfoperating leverior vhandle 16V is pro- 80 vided for themanipulation of thehoist and i is so arranged with respectltotheclutchand brake mechanisms thatuneither will interfere with, the operation ofthe other. Thatis tosay,the clutch and the brakeoperate indi- 85`vidually land such operation is controlled by Y the y,single manuallyoperable handleV or lever 16 jwhich upon movement .in one directioneects ai drivingjengagement betweenthe f adaptedv to be securedpermanently upon the wheelto which end a pluralityiof U-shaped n bolts18are appropriately disposed about the outerperiphery of the lring to beiitted around certain of thevspokes v19 of the wheel. 100

vides a bearing upon` vwhich provide three separate external bearingsurfaces, of which the inner and the largest diametered surface 2Oprovides a surface upon y which they brake device is mounted, the outerYand smallest di'ametered surface 21 -providesfa mounting "for theclutch device 14, and theinter'mediatesurface 22, the diameterlof'whichis intermediate the diameters of the brake and clutch surfaces,prothe drum as- `semblyv13 is mounted, y TheV shafty 12 adjacent theinner end has van integrally formed-radial flange 23 thereon'arranged toabut the ring 1-0 on the wheel 11'.v The fla-nge 23 is spaced a shortdistance from the end of the shaft to lprovide an axially extendingshoulder 24 which is accurately machined orV otherwise finished to "fitsnugly within the correspondingly finished inner periphery of the-ring.y A

The shaft may be securely mounted on the ring through the ilange23 invany preferred manner, as byy providing a plurality of outwardlyprojecting studs 25 on the ri-ng 10, whichv `studs extend throughappropriately positioned apertures 26 in the flange 23.V The studs arescrew threaded at 4their outer ends toreceive a nut 27 thus securing theshaft 125 to the ring 10. By this construction vthe shaft-may beproperly positionedonthe ring by the abutment of the shoulder 24 and theflange 23 with the ring and thenbe rigidly secured vin place lwith aminimum expenditure of time andlabor. Since the ring has beenpreviouslytrued with respect tothe wheel, the shaft will also be accuratelimounted on the wheel. As maybeSeen in the drawings amplespace'isprovided within the brake sectionof the drum to receive therein 'the'hub-capassemblyof any vehicle.

'The drum assembly 13in thisV instance comprises a central portion orhub28 having a pairY of spaced outstanding eircul'arwalls 29, 30 thereon.'T'The drum is somewhat shorterthaln2 the hub 28, which is substantiallyas long as the intermediate section 22 of the shaft',v thus providing anextensionwhich,

. in effect, isanaxialfsleeve 31A integral with the drum.V The sleevei's-arranged to be engaged; by a pa-rt'of the clutch mechanism as willbe presently-described The outer wall.

^ofgthe drum preferably carriesthereon a i means by, which one end of acable: 32fma-y be secured'to the hoist. Thisfmeans-as shown in Fig. 1comprises a bolt 33 permanently mounted on the wall 30 to extendoutwardly therefrom and is screw threaded to receive a V nut 34, betweenwhich and the wall of the drum the cable 32 may be secured. Since thecable is thus secured'externally of the hub of the drum a suitableaperture 35 is provided in the wall through which the cableV may bepassed to be wound on the drum. In this construction the aperture ispositioned relative to the securing means in such manner ,that the cable32 will be drawn onto and released from the lower side of the drum.

The clutch mechanism 14 may be of any preferred construction which willprovide a positive driving engagement between the shaft 12-and the drum'13. In this instance I have showna clutch mechanism comprising anengaging member. in the form of a split collar 36 (Fig. 4) which ismounted relatively loosely on the sleeve 31 of the drum 13. The collar36 is adapted, when the winding drum is at rest, toA rotate loosely uponthe sleeve-31 and is formed of a suitable somewhat resilient materialwhichnpermitsthe split ends 37, 38 of the collar `to be drawn togetherthereby tightening the collar tol such an extent thatza frictionalengagement between the sleeve 31 and the collar l 36 is produced. At asuitable position upon. the-col.- lar, which, inthis instance, isdiametrically opposed to the gap. therein,r an integral radial lug39 is;provided which projectslaterally beyond the sidesof the collar.. Thelaterally proJecting portion is notched, as at 40,1.; to

described.

A plate 41 of substantial thickness4 and preferably circular in shape.is mounted about thel smallest diametered or clutch Section 21 of thevshaft adjacent the outerfend of the intermediate section 22 carryingfthedrum. The plat-e is. secured to the shaft, 12 for rotation therewithbyany suitablemeans, suchfas the key 42. On one side of the plate aradially extending Vfinger 43" is; formed which is adapted to extendinto and beengaged by the notch 4Q in. the laterally pro,- jectingportion ofthe collar. In this, manner, at driving connection with, theVshaft is provided for the collar.V

The preferred form lof the means by which the split" ends 37, 38` of thecollar 36 are drawn together to engage the collar with, the drum slee-ve31 is `shown in Figs. 2 and' 4. On one split endk ofthe collar, in thisinstance the end 37 ,a pair ofaxially spacedlugs 44 are, provided whichhave registeringopenings therein to actas bearings for apin 45'.

a base permanently attached to said'prime mover for rotation therewith,a shaft adapted to be'mounted on said base with the axis of said shaftin alignment with the axis of said prime mover, means for detachablysecuring said shaft to said base, adrum rotatably mounted on said shaft,and means controlling the movements of said drum relative to said shaft.

17. A device of the character described4 comprising, in combination witha driving means having a base permanently mounted thereon, a shaftadapted to be .mounted on said base, interengaging means on said shaft Yand base for definitely positioning said shaft the combination of adriving means having l on said base so that the axis of said shaft willbe in alignment with the axis of said driving means, means fordetachably securing said shaft to said base, a drum rotatably mounted onsaid shaft, and means controlling the movements ofY said drum relativeto said shaft.

18. In a device of the character described,

an annular ring mounted thereon concentrically with respect to the axisthereof, and a hoist mechanism adapted to be detachably o secured tosaid ring including a shaft having an annular flange thereon concentricwith respect to the axis of said shaft, said ange being of such size asto snugly abut said ring when said shaft is mounted thereon whereby theaxis of said shaft is definitely located in alignment with the axis ofsaid v driving means, and means for detachably securing said shaft tosaid ring.

In testimony whereof, Ivhave hereunto affixed my signature.
